Dyna-Flo II. The ultimate in high-volume cleaning
Stage 1
Four conveyor augers are located beneath
the concave, where the volume of separated
material is highest to evenly move material
into the cleaning system. Note the deep
auger troughs; they provide uniform
distribution of material to the cleaning
system with less bunching, even on side
slopes even when ascending or descending
hills the augers move material evenly and at
a set pace on to the cleaning shoe.
Stage 2
The new Dyna-Flo II cleaning fan blows a
high volume of air across the full width of
the cleaning shoe with an improved air
distribution between the front and rear part
of the cleaning shoe. About 30% of
high-velocity air fl ows to the front chaffer;
70% of high-volume air is guided to the rear
chaffer and sieve. A steep pressure curve
delivers high pressure with less volume loss.
The result? Maximum effi ciency and a clean
grain tank sample.
Stage 3
Material from the separator is pre-cleaned
in two stages. The front fi xed chaffer is the
fi rst step before reaching the main sieve,
helping to thin the crop mat. The raised
front chaffer pre-cleans up to 40% of free
grain before it reaches the rear chaffer. Air
from the cleaning fan elevates any light
material travelling over the end of the raised
front chaffer. This results in more aggres -
sive separation of material at the step pan
and increased cleaning performance.
Stage 4
The two-piece front and rear chaffer and
the single-piece sieve are designed
specifi cally for the S-Series combine. This
robust design allows our cleaning shoe to
operate at a longer stroke and higher speed
than other combines. The result: a
high-performance, compact design that
reduces slope sensitivity while delivering
perfect results – proving again how our
intelligent design makes the difference for
you.

Side Hill Kit helps prevent grain loss on slopes.
If you’re concerned about grain sliding to the downhill side of the combine and overloading one side of the cleaning shoe, don’t worry. Our Side Hill Kit helps hold grain
to each part of the shoe. That allows more grain to fall through to the sieve and help eliminate any grain loss from driving on hillsides.
